I was looking at the "Creamy bokeh" thread and I noticed a few images that I would not call exactly creamy. Creamy to me implies a certain soft/dreamy nature of the defocused background and foreground. Not all lenses render the out of focus areas in the same way and certainly not all of them are creamy. Often modern lenses have a neutral bokeh, or a nervous one, only some are creamy. Vintage adapted lenses can have creamy bokeh but often also can give bubbles in speckled highlights.
While it's difficult to describe in words a look of a certain bokeh, I think here would be a good place to show something that you regard NOT creamy.
Let's see bubbles, squares, doughnuts and all the weird bokeh that make some people cringe and other amazed. It's all in the eye of the beholder, right?

a classic example of bokeh balls from speckled highlights rendered by a Helios 44
The lens was sold to me from Russia (eBayer PhotoMoscow) as Helios 44-7 but it was a fake 44-7; it was just a 44 dressed up as 44-7. It just isn't as sharp but the bubbles are there

The Trioplan 100mm has such clean beautiful soap bubbles, but it costs so much I always wanted one..

I wanted the big bubbles too so I sourced a very (extremely) cheap lens that I was hoping would give me bubbles.
A projection lens from a Kodak Carousel seems to work, but the bubbles are different, not so distinct and sharp

ah, is that how the M.Zuiko 300mm f4 renders the bokeh? semi-creamy but a bit nervous... of course, at this distance and this subject/background separation
In your Flikr upload you have it in the MC-14TC album; it that correct? can you recall the f-stop?

It was the M.Zuiko 75mm f1.8 that started my quest for "bubbles". It was not my lens but in one weekend I used it I realized I wanted more. Your bubbles from the Zuiko are very nice, better than what I could get. I think I didn't know yet that speckled highlights are the trick to good bubbles

Both of those pics were taken when the sun came out just before sunset after a day of rain, providing backlighting for all the water droplets. I saw it through the window and grabbed the camera. It was a pretty magical moment that only lasted about 7 or 8 minutes before the sun went down.

I have been seen walking around with a spritz bottle (repurposed pump-action sunscreen mist-spraying bottle) and wet the plants on a low setting sun .
It kind of works for real close ups but I would need a bigger bottle for large scenes.
I carried one on a 3 day backpacking trip where I knew the dew would have evaporated way before I would get to some nice subjects (it's pretty dry here in Australia)

It was f/6.3. And with the MC-14. I was at my bird pond and closing in on a bird when I saw these wild grain? stalks. I have got some weird bokeh with this lens, but after using the 40-150 f/2.8 a ton, I kind of expect it.

a bokeh that defies all aesthetics?

only the very centre of the image circle is almost sharp, the rest is just fuzzy and swirly
